Edu,
Si necesitas un diseño práctico, échate un vistazo al diseño de referencia de IRF, es un sigma-delta bastante sencillo.
Mira también el proyecto de Sorensen (Sorensen Audio Experiment). Tiene alguna introducción teórica y algún diseñillo práctico muy sencillo.

Oooops!
sorry: a Spanish member is not an usual thing! Translation: if you need a practical design, have a look at IRF's reference design. Read also the Sorensen Audio Experiment pages about sigma-delta modulators, they have some simple practical designs as well.

Un saludete!

Best regards,
Sergio from Madrid
 
Gracias Sergio.

Mas o menos llevo un tiempo mirandolos pero hay un par de cosines aun que no entiendo demasiado bien.(More or less I spent aome time looking at them, but there are a couple of things that i don¡t understand to much)

Is there any modulation rate in sigma-delta modulators as in PWM ones?

In that case, how do I stablish the modulation rate?

Read you soon.
Edu.
